Hero4 Session -- the smallest, lightest and most rugged GoPro video camera to date.
The Session has a new cube-shaped form factor that distinguishes it from its earlier, more rectangular GoPro siblings such as the Hero4 Silver and Black . It's also 40 percent lighter than those models and that square shape, included mounting frames and quick-release buckles let you rotate the camera so it's right-side up and lower profile, something that's not easily done with other GoPro cameras. Another Session difference is that it's waterproof down to 10 meters (33 feet) -- without the need for an enclosure. By contrast, the Hero4 Silver and Black are almost twice as bulky when snapped into the wraparound housings that are required to keep them dry.
